Descriptions

In PHP before 5.6.30 and 7.x before 7.0.15, the PHAR archive handler could be used by attackers supplying malicious archive files to crash the PHP interpreter or potentially disclose information due to a buffer over-read in the phar_parse_pharfile function in ext/phar/phar.c.

En PHP anterior a versión 5.6.30 y versión 7.x anterior a 7.0.15, el manejador de archivos PHAR podría ser utilizado por archivos maliciosos suministrados por los atacantes para bloquear el intérprete PHP o potencialmente divulgar información debido a una lectura excesiva de búfer en la función phar_parse_pharfile en el archivo ext/phar/phar.c.
